Point well taken. As the population increases the food supply must increase. Most easily aided by chemical control of pests on the crops. There is definite value in control of mosquitoes and other disease carrying insects.
But I don’t believe insecticides are microscopic or incidental to human health.
It’s a catch 22..We have better crops and fewer vermin. We also ingest these life saving measures with the creatures we aim to chemically kill. In the form of run off to water sources, air quality, the food we eat, etc.
If nobody picked and chose between risks every day, we’d all be trapped in our beds paralyzed in fear. I know that one thing that almost all of us want and prize carries a huge risk of cancer... and that thing is a long, long lifetime.
